[Aruma] How to Train your Little Sister! (COMIC LOE VOL.10 Mini LO 4 Jikanme) [Team Rabu2]

An eager brother races home to his adorable little sister, who is decked out in playful twintails and a cheeky "TUNA" shirt, determined to drag her away from her studies for some questionable "training." The tension between his desire to mold her into his ideal cutie and her innocent, squealing resistance sets the stage for an intensely intimate conquest that escalates with every touch. As the older brother takes full advantage of his tiny, trembling onii-chan in increasingly dominant positions, the story culminates in a heated creampie finish that leaves both siblings breathless and craving more.
